SPEGIFICATION forming part of Letters Patent 170,704,055., dated July 8,1902. Application filed August 31, 1901. Serial Nog. 73,987. (SNOmodel.)

To all whom vit may concern:

Be it known that I, CARL v'l`1}1ISll\H31`t, a subject of the Emperor ofGermany, and a resident of 22 Bloomeld Road Bom-London, E., England,have invented a new and useful lmprovementin Machines for Making GlassBottles, of which the following is a specification.

This invention relates to machines for making glass bottles by castingthe head or neck and then blowing the bottle in suitable molds; and itconsists in certain novel combinations of parts hereinafter describedand claimed.

The leading object of the invention is to provide means for makingbottles by machinery with greater speed than has heretofore beenpracticable.

Other objects are to provide by improved means for shaping the lip andmouth wholly bycasting; for rotatingthelumpofglass within theparison-mold; for swinging the parison in the open air, as 4inmouth-blowing; for making turned bottles, if desired; for insuringagainst injury to the bottles by excessive air-pressure; for controllingthe rotation of the glass and the admission of air by one and the samehand; for simultaneously opening and closing the parison and blowingmolds, and for delivering each blown bottle at once, so as to free themachine for the succeeding operation. K

Eight sheets of drawings accompany this specification as part thereof.

Figure 1, Sheet 1, is a side elevation of the improved machine,showingthe parts in working condition with the molds closed. Fig. 2, Sheet 2,is a face View with parts omitted, showing the mold-supportsy open. Fig.3,

Sheet 3, is a face view with parts omitted,`

is a diagrammatic plan View illustrating the Figs. 11 to discharge ofthe blown bottles.

19, inclusive, are fragmentary detail views,

hereinafter more particularly described.

Like letters and numbers refer to like parts in all the figures.

The improved machine has an upright frame-piece a, Figs. 1 and 11,having a substantial foot or base 1, a planed face 2, a longitudinalslot 3, and two or more bolt-holes 4 as its distinguishingcharacteristics. To the planed face of the frame-piece d at a heightbest suited to the operative who is to work the machine a frame-plate b,Figs. 1 to 3 and Fig. 11, is adjustably fastened by bolts 5, extendingthrough said bolt-holes in the former, and provided with lever-nuts 5aor the like behind the frame-piece@ Fig. 11, Sheet 2, represents ahorizontal section through said parts a and b on the line E F, Fig. 2.To hold the heads of said bolts 5 at any height and to hold in likemanner the heads of attaching-bolts 6 at the front of the machine, theframe-plate b, both sides of which are planed, is provided lengthwise ofboth sides with undercut or T grooves 7 and 8, Fig. l1. KAt abouttwo-thirds the distance from its lower end the frame-plate b is providedwith a holeyQ, Figs. 2, 3, and 11, to coincide withfsaid slot 3 in theframe-piece a, and the sides of said hole 9 are provided with lateralprojections 10, to which at the face of the machine a bracket-likepillow-block c, Figs. 1, 6, 7, and 11, is fixedly bolted. Thispillow-block c is provided with brasses 11 and 12 and caps 13 and 14,Figs. 1 and 5 to 7, and within the same a hollow horizontal hub d isrotatively mounted, with peripheral bearingsurfaces 15 and 16 iitted tothe respective brasses and with its rear end 17, Figs. 6 and 7, out ofcontact with and a short distance removed from thegface of theframe-plate b.

Within the concentric chamber 18 of the hub CZ a short sleeve-shapedsupport e, Fig. 7, normally concentric with the hub, is mounted to rockon a pair of pivot-screws 19, diametrically opposite each other andnormally horizontal, to form a rocking bearing and lis providedinternally with brasses`20 and 2l.

Within the brasses 2O and 2l a short hollow shaftf, Figs. 5 to 7, isrotatively mounted and is held in place against endwise displacement bya peripheral shoulder 22 and a fast collar 23, Fig. 7.

ICO

A continuously-driven sprocket-wheel g,

Figs. 1, 6, and 7, is fast on the rear end of the hollow shaft f betweenthe rear end of the hub d and the face of the frame-plate b, 5 and itsfrontend carries a beveled frictionwheel h, normally equidistant fromand out of contact with the beveled peripheries of apairofadjacentfriction-wheelstandj. These latterare seated on therespective ends of a 1:0 short recessed body portion d', hereinaftertermed the neck-mold carrier, that is integral with the hub d, its seats24 and 25, Figs. 4 and 5, for said wheels t' and j, respectively, beingparallel with the plane of the pivots 19 and, like the latter, normallyhorizontal. A central screw-threaded socket 26, Figs. 5 and 6,perpendicular to each of said seats 24 and 25, receives the threaded endof a large conicalpivot 27, around which the zo wheel t' or j revolvesand which is recessed axially to form an air-cylinder for a hollowpiston 28, Fig. 5. This piston 28 carries a normally protruding andsolid mouth-.core k, preferably and conveniently detachable therefrom,as shown, to render it interchangeable with mouth-cores of other shapesand sizes. A lip-molding screw-ring Z, Fig. 5, likewise interchangeablewith others, limits the protrusion of each mouth-core. Protrusion may 3obe eected either by a spring 29, Fig. 5, or by air-pressure. The'spacecontaining the spring 29 is connected with the atmosphere by a vent 30.

A bisected neck-mold m, Figs. 4 to 6, is attached to the hub 'n of eachof the wheels 't' andyby the diametrically-arranged bolts 3l, by whichthe parts of the mold are hinged to cach other. Lugs 32 onthe'mold-housing aline the mold parts with each other, and 4o spiralsprings 33, Fig. 4, render the mold normally closed. Rod-sockets in thehub n are shown at34, Fig. 4, to provide forturning the mold into itsopening position by hand, if need be, and an annular end groovein themoldhousing is shown at 35, Fig. 5, as means for opening the mold. Thesprings 33 are conveniently compressed between the face of the wheel iorj and the opposing end of the mold and are securely held inpartially-inclosing 5o sockets 36 therefor in the mold-housing.

Each neck-mold is provided with a twopart lining 0, Fig. 5, the interiorof which imparts the required shape to the head of a given size andstyle of bottle, such linings being interchangeable for others havingmatrical cavities of different sizes and shapes. The linings are heldtightly in place within the mold-housings by screws 37, Fig. 4.

The air-pipe p, Figs. 1, 5, and 7, enters horizontally from behind theframe piece a through the slot 3 in'the latter and the hole 9 in theframe-plate b and through the interior of the hollow shaft f, beingscrewed fast at its inner end into a valve-chamber 7, Figs. 5 and 7, inthe neck-mold carrier d in line with the axis of the hub d.Aswivel-couplng 3S, Fig. l, permits the inner length or section of theair-pipe to turn freely with the 'hub d and neck-mold carrier d aroundits own longitudinal axis.

A peculiarly-recessed spigot-valve r, Figs. 1 and 4 to 7, is ttedintothe valve-chamber q and operated by a lever-handle s, being held to itsseat by the screw-cap of a stuffing-box t at its outer end. When thehandle s is turned toward either neck-mold, as in Fig. 5, the air ispermitted to pass from the pipe p through an end recess 39 and a radialport 40 of the valve into and through a central tube 4l, to which thechamber of the corresponding hollow piston 28 is fitted, and throughports 42, leading from this chamber into the space between the pistonand the corresponding lip-molding ring Z. Reacting against the opposingsurfaces of these parts the air forces the piston 28 into its retractedposition, as at the bottom in Fig. 5, and retracts the outer end of themouth-core 7c into the plane of t-he ring, having an annular passagebetween the core and ring,vso that the air may pass freely around thecore into the cavity left thereby in the glass to blow the bottle.

To prevent excessive air-pressure within the bottle, an axial chamber 43in the outer end of the valve r is provided with a plunger 44, a spiralspring 45 behind. said plunger,

and a regulating-screw 46 behind the spring,-

and passages 47 and 4S are formed in the wall of the valve-chamber q andin the valve, whereby the air as it enters the piston-chamber is causedto act on the end of the pressure-regulating plunger44, which byreceding more or less against the resistance of the spring 45 reducesthe air-pressure to the standard, the resistance of the springequalizing the air-pressure.

A modification of the valve r is shown by Figs. 12 to 14, Sheet 5, whichrepresent, respectively, a longitudinal section, as in Fig. 5, and endviews of parts. As shown in these figures, a puppet-Valve 44LL takes theplace of IOO IIO

the plunger 44 and a hollow screw 46a takes the place of the thumb-screw46, so that the valve may act as a vent for the escape of air when thepressure is excessive.

To adapt the lever-handle S,Figs. 4to 7 and Fig. 15, to serve not onlyfor the air-valve r, but also as means for throwing the frictionwheel hinto mesh with the wheel t' or the wheelj at will to rotate either ofthe neckmolds fm, the lever-handle has a transverse hinge-joint 49, theaxis of which is parallel to the face of the machine and normallyhorizontal, and a fork 50 is rigidly attached to the hand end of thelever, so as to loosely embrace the socket-piece 5l of the same, whichis secured on the squared outer end of the valve fr by a nut 52 incustomary manner. Fig. 15, Sheet 4, is a fragmentary side View of saidlever-handle s and its connections.

The fork 50 is connected by a pair of links 53, Figs. 4 to 6 and Fig.15, with a swivelring 54, which occupies a peripheral groove in a ring55, concentric with the valve r.

i tates the lower neck-mold and its appurte` A pair of rods 56 extendrearwardly from the ring 55 through guide-holes in the neck-mold carriercl and terminate at their rear ends in inclined forks 57, Figs. 5 and 7.

These forks 57 embrace beveled lugs 58, diametrically opposite eachother on a swivelring 59, and the latter is secured against endwisedisplacement around the hub of said friction-wheel h and against itsback by a screw-ring 60. The neck-molds being in normal position, as inFigs. 4 to 7, with either neck-mold at top and the lever-handle s in anyposition, an inward thrust of the leverhandle, acting through the fork50, links 53, rings 54 and 55, rods 56, andr ring 59, rocks the sleeve eon its pivot and presses the wheel h into mesh with the wheel i (or j)and rotates the upper neck-mold and its appurtenances. In like manner apull on the lever-handle s depresses the wheel 7L and ronances. A handle6l, Figs. 1, 4, and 7, projecting rigidly from the neck-mold carrier d',provides for turning the latter, and therewith the neck-molds m, aroundthe axis of the hub d to reverse the neck-molds and to swing the parisonthrough the air, as hereinafter described.

A parison-mold m', Fig. 1 and Fig. 8, is located above the neck-moldcarrier d to coact with the neck-mold m that is for the time beinguppermost, and a finishing or blowing mold m2, Fig. 1 and Fig. 8, isarranged beneath the neck-mold carrier tocoact with the neck mold thatis for the time being at bottom. These molds, in common, compriselongitudinally-bisected housings and linings, the latter interchangeablewith others in the manner above described with reference to theneck-molds m, and are in common mounted and operated as follows Foi-eachof said molds m and 'm2 a bracket u, Figs. 1 to 3, is attached by a pairof said screws 6 to the face of the frame-plate b and is constructedwith lugs 2 at top and bottom, through which a hingerod 63 extends.Hinged to such rod ateach mold a pair of mold-supports 64 are adapted tocarry the respective parts of each mold horizontally into and out ofcontact with each other. Horizontal slots 65 in each mold-support coactwith bolts 66 therein and also with planed seats 64, Fig. 10, for thesupports across the several mold parts to adjust the latter intoalinement with the parts of the neck-molds 'm and the several molds intoalinement with each other and also vertically.

Both the molds m and m2 are closed simultaneously by depressing atreadle 67, Fig. 3, a bottom view of which is represented by Fig. 16,Sheet 3. This treadle is pivoted to a bracket o, which is adjustablyattached to the face of the frame-plate b at bottom by a pair of thebolts 6 and is connected by atension-rod 68 with an endlesssprocket-chain 69. This chain embraces a pair of sprocket-wheels 70,rotatively mounted on central stud-shafts within the brackets u, andeach sprocketwheel is connected by miter-gearing 71, Figs. 1 and 2, withthe pair of mold-supports 64.

A spring .72, Fig. 3, stretched from the bracket o and connected by atension-rod 73 with the endless sprocket-chain 69, serves to 'open themolds 'm' and m2 simultaneously when the treadle 67 rises and to renderthe molds normally open.

To coact with the upper ends of the rods 68 and 73, side portions 74,Fig. 3, of the endless chain 69 may be in the form of rods or plates,and said rods 68 and' 73 may be connected thereto by pivotal studs 75 orany suitable couplings. 3, provides for keeping the chain taut.

A beveled spring-bolt 77, projecting from the upper end of each of thehalves of the blowing-mold m2, as in the sectional detail, Fig 17, Sheet4, so as to project into the groove 35 of the bottom neck-mold, mayadapt the blowing-mold to open the neck-mold sufficiently for the escapeof the blown bottle downward therefrom as the blowing -mold opens. Theblown bottle is thus lowered by a peculiarly-operated mold-bottom m3,Figs. 1 and 2, a sectional detail of which is shown by Fig. 18, Sheet 2.A bracket fw therefor, Figs. 1 to 3 and Fig. 19, is adjustably attachedto the face of the frame-plate b by a pair of the bolts 6 and has at itsouter end a vertical guide portion 78, within which the stem 79 of saidbottom m3 is movable vertically. A lever-handle 80, Fig. 1, is connectedby a horizontal pivot 81, Fig. 18, with a toothed sector 82 within aslot in the outer portion of said bracket, and a rack 83, attached tosaid stem 79, meshes with the sector.

A central screw 84Fig. 18, removably attaches the mold-bottom m3, so asto render it, in common with the mold-linings,interchange*- able forothers of dierent patterns and sizes, and a hinge 85, Figs. 1, 3, and18, both leaves of which are normally horizontal, provides for tiltingthe bottom to discharge the blown bottle therefrom, as in dotted linesin Fig. 10. In connection with such tilting bottom the bracket w isconstructed with a hinge 86, the axis of which is Vertical, andprovision is made for automatically swinging the outer portion 87 of thebracket, anditherewith the mold-bottom m3 and a bottle carried bythelatter, to said dotted-line position in Fig. 10. This is effected by thecoaction of a slotted portion of the treadle-rod 68, Fig. 3, with onearm of a bell-cranklever pivoted to the fixed portion of the bracket wand carrying at its other extremity a pivoted pusher 88, which isrendered adjustable by a stop-screw 89, Figs. 3 and 19. The par-ts areshown in their positions of rest in Figs. 2 and 3. When the treadle 67is depressed,the rod 68 moves the lever into the alternative position inwhich it is shown in Fig. 19, Sheet 3, which is areproduction of aportion of Fig. 3 with the parts in different positions. Such movementof the A turnbuckle 76, Fig.

lever :n retracts the pusher 88 and permits the swinging portion of thebracket w to be brought by means of the lever-handle 80 lagainst anadjustable back-stop y, Figs. 1, 3,

l0, and 19, which alines the mold-bottom m3 with the neck-molds mpreliminary to closing the molds m' and fm2. Y

f The method of producing bottles in and by the improved machine isillustrated by Figs. 8 to 10, as aforesaid.

With the parts properly adjusted and the parison and blowing moldsclosed, as in Fig. 1, lthe operative holds down thetreadle 67 by` hisleft foot (or this may be done by a mechanical detent) and starts withthe leverhandle s in horizontal position, which cuts 0E the air at thevalve r. The attendant now puts a lump of the molten metal (hereintermed the glass in the parison-mold m', and the same immediately fillsthe upper neck-mold m, flowing around the mouth-core.

lo within the same and into contact with the subjacent lip-forming ringZ, as at the top in Fig. 8. The friction-wheel h being in motion, asrepresented by the arrow 90,]`igs. 8

and 9, the operative now presses inward the lever-handle s, pulling rods53 outward, and causes said neck-mold, and therewith the parison X, torotate, as indicated by the arrow 91, Fig. 8. Such rotation of theparison in contact vwith the interior of the relatively stationaryparison-mold m' tends to render its exterior homogeneous and to take theplace of marvel-ing. The parison and blowing molds m and m2 are nowopened, as represented by the arrows 92, Fig. 8, and the newly-exposed.parison X', Fig. 9, is swung around the horizontal axis of the hubd bythe handle 61 of the neck-mold carrier, as represented by the arrow 93.At the end of this movement the parison hangs exposed at bottom, asshown in dotted lines at Y, Fig. 9. The lever-handle s is now turneddownward and air is admitted through the valve 'r' to the mouth of theparison, as represented by the arrows 94E. Should the parison fail toelongate as soon as air is admitted,itis swung by means of the handle61, as represented by the arrows 95 and 96, Fig. 9, as in mouth-blowing.As soon as the depending parison is ready for the blowingmold the moldsm' and m2 are again closed, as represented by the arrows 97, Fig. 8, andthe mold-bottom lm3 is elevated to its effective vmolding position, asrepresented by the arrow 98, Fig. 8. The blowing of the inclosed hollowparison Y', Fig. 8, is then completed, the cushioning-plunger 44 orvent-valve 44 within the valve r serving meanwhile to prevent excessiveair-pressure. Such regulation of the air-pressure is of specialimportance in blowing turned bottles, as onlya certain airpressure canbe used in this operation. EX- cessive or irregular air-pressure pressesthe glass so tightly against the walls of the blowing-mold as to preventturning the bottle. For making turned bottles it is only necespleted,the molds are opened again, (arrows 92,) and the lower neck-mold fm,opening with vthe blowing-mold m2, as represented by the arrows 92a, theblown bottle Z, Fig. 10, is released, so as to be lowered with themold-bottom m3, as represented by the arrow 100, Fig. 8. Meanwhile theparts of the blowing-mold m2 swing wide apart, as shown in Fig. 10, andthe laterally-swinging support of the bottoni m3 is thrown to the left,as above described with reference to Figs. 1, 10, and 19. Said lateralmovement is vrepresented by the arrow 101, Fig. 10. The bottom m3 isthen tilted, as

. shown in dotted lines in Fig. 10,and the bottle Z is deposited in anasbestos-lined receptacle a, Fig. 10, at its higher end, from whence itrolls to a position of rest in the receptacle, as represented by a blownbottle Z', to be rep moved to the annealing-oven at convenience.

The return movement of the bottom m3 is represented by the arrow 102,Fig. 10.

By reason of the organization of the improved machine as above it is notnecessary for any one operation to wait on another when makingbottlesvnot turned, no time is lost, and the output of a given operativeis materially increased.

The handle 61 may project from the lefthand side of the neck-moldcarrier d', so as to bring the lever-handle s opposite the right handwhen the valve r is shut, or a handle 61 may project from each side, andother like 1 modifications will suggest themselves to those skilled inthe art.

III' it were not for swinging the naked parison through the air, itwould be practicable to admit air into the same before it is reversed bysimply turning the hand-lever s upward toward it. The blowing may thusbegin in modifications of the improved machine.

The term air as herein used is intended to include other bottle-blowingiiuids-as, for example, steam.
